VAPORIZER.

SPECIFICATION forming part of Letters Patent No. 453,818, dated June 9,1891. Application filed November 4, 1890. Serial No. 370.357. (N0model.) Patented in England November 30,1889, No. 19,262.

To all whom it may concern:

Be it known that I, \VILLIAM HENRY MUR- RAY,chemists assistant, of 15Mayfield Villas, Merton Road, \Vandsworth, in the county of Surrey,England, a subject of the Queen of Great Britain, have invented anImproved Apparatus for vaporizing Medicines, Disinfectants, Perfumes,and other Substances, (for which I have made application for LettersPatent in Great Britain, No. 19,262, dated No vember 30, 1880,) of whichthe following is a specification.

This invention consists of an apparatus or contrivance for vaporizing byheat-such as from the flame of a gas or other suitable burner or lamp,for instance, aspirit-lamp any suitable medicines, chemicals, orchemical compounds for medicinal purposes or 0th- Wise, such asdisinfectants and perfumes, &c., or for vaporizing or burning any othersubstances or materials, as desired-for instance, insect-destroyers,microbe-killers, &c.-and for which it may be suitable.

The chemicals oringredicnts are contained in a kind of flask or holderof any suitable material, (but advantageously made of glass,) and thisholder or vessel is placed in the center part of the apparatus orcontrivance which forms the subject-matter of the present invention, andwhich I will now proceed toifully describe with reference to theaccompanying sheets of drawings, so that the said invention may be fullyunderstood and readily carried into practice.

Figure I represents a side view in elevation of the said apparatus orcontrivance and heated by a gas-jet on the well-known Bunsen burnerprinciple. Fig. II is a vertical central section of Fig. I. Fig. III isa plan of Fig. I with the double shield or cover removed. Fig. IV is asimilar apparatus only heated by a spirit-lamp instead of by a gasjet,as in Figs. I to III.

a is the bottom or supporting framemountcd on legs a and carrying thegas-pipe b, the turned-up end Z) of which forms the burner. Upon thisframe a is placed the flask c or other convenient vessel which containsthe chemicals oringredients to be vaporized, and over this flash 0 isplaced the double casing (Z and c, the inner part (Z of which completelycovers the flask or vessel 0 and forming an annular space no betweensaid inner case ('1 and the outer wall .0 and top 6. The burner orheat-producer is mounted in this annular space a", between the innercasing (Z and the outer casing c, and air to support combustion isadmitted through suitable openings below, while the products ofcombustion can escape through suitable openings f andf in the easing orouter wall 6, these holes f and f being of such a size that a warm bodyof air is retained in the space ,r. The flame from the burner thusproduces a constant heat (subj ect to regulation) around the flask orchemical-holder c, and so vaporizes the contents which pass out up thepassage or chimney (1 into the room or compartment in which theapparatus is in use.

Fig. IV shows an equivalent apparatus, only the heat-producer in thiscase is a spiritlamp, the reservoir or vessel 9 for holding the spiritsforming the base or stand upon which legs a of the apparatus aremounted.

All the other parts are identical or equivalent to those previouslydescribed.

It will be obvious that the apparatus may be made of any size andproportions or di mensions, according to requirements, and

any suitable material or materials may be used in the constructionthereof, though it may be mentioned that brass or copper will be foundvery advantageous for forming the parts (Z d and c e, which. lattermaybe formed all in one part, as shown, or in separate parts, ifdesired.

The form or shape of the apparatus maybe varied, if desired,

The arrangement of the shield or wall (1 between the burner orheat-producer and the vessel 0, containing the chemicals, dsc, is ofgreat importance and forms an essential feature of my present invention.

Having now particularly described and as certained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is- I. In a vaporizer, the combination, with an exteriorcasing closed at the top, of an interior casing in said. exteriorcasing, a burner at the side of the interior casing and in the spaceporized in said interior casing, and a burner between said interior andexterior casings, between said interior and exterior casings, and avessel in said interior casing for receivsubstantially as set forth.
